Not Otherwise Specified?
• 147/165 ED patients diagnosed with EDNOS (May 2007)
• The majority of patients with Eating Disorders are given a diagnosis without specified criteria

Anorexia – A Life Threatening Illness
• Anorexia Nervosa has the highest mortality rate of any psychiatric disorder. The most common causes of death are complications of starvation and suicide.
• The mortality rate at five years is 5%, increasing to 20% at 20 years F/U (APA 2000)
• The highest predictor of mortality is?

Eating Disorders and Substance Abuse
• One of the strongest and most consistent predictors of fatal outcome for patients with Anorexia Nervosa was severity of alcohol abuse during follow-up!
![Page 6: Eating Disorders and Substance Abuse](https://reader035.vdocuments.us/reader035/viewer/2022062500/5681525f550346895dc092bc/html5/thumbnails/6.jpg)
The highest rates of suicide attempts are reported among bulimic individuals who have co-morbid alcohol abuse (54%).
(Eating Disorders 2002; 10:205)

Eating Disorders and Substance Abuse
The National Center on Addiction and Substance Abuse (CASA)– between 30 and 50% of individuals with
Bulimia Nervosa abuse or are dependent on drugs or alcohol
– 12-18% with Anorexia Nervosa abuse or are dependent on drugs or alcohol
– compared with 9% of the general population
![Page 8: Eating Disorders and Substance Abuse](https://reader035.vdocuments.us/reader035/viewer/2022062500/5681525f550346895dc092bc/html5/thumbnails/8.jpg)
Eating Disorders and Substance Abuse
• 35% of people who abuse drugs and alcohol have an eating disorder, compared to 3% of the general population.
![Page 9: Eating Disorders and Substance Abuse](https://reader035.vdocuments.us/reader035/viewer/2022062500/5681525f550346895dc092bc/html5/thumbnails/9.jpg)
• The lack of awareness and understanding of the link between eating disorders and substance abuse has led to limited treatment options for patients.

Similarities Between ED and SUD
1. Life Threatening
2. Chronic Relapsing Course
3. Long Term
4. Compulsiveness
5. Ritualistic Behaviors
6. Resistant to Treatment
7. Begin with experimentation; only a small percentage lose control
8. Lead to chronic compromised nutritional and medical complications

DIFFERENCES - CRAVINGS
Alcohol/Drugs
• Driven by the on-going craving to get another drink or drug.
Eating Disorders
• Driven by the need to avoid or overcome the substance (food).
• Driven by the feeling following binge
• Driven by the feeling following purge

Treatment Philosophy
• While substance abuse and eating disorders have much in common, their treatment is based on very different philosophical approaches.
![Page 14: Eating Disorders and Substance Abuse](https://reader035.vdocuments.us/reader035/viewer/2022062500/5681525f550346895dc092bc/html5/thumbnails/14.jpg)
Treatment Philosophy
Alcohol/Drugs
Recovery• Restrict or abstain from
substance.
Control
• Abstinence – external imposed structures of control.
Eating Disorders
Recovery• Food as ally to sustain
life.
Control
• Inner Strengths with little external controls.

A majority of young woman diet at some point in time yet only a small fraction develop eating disorders.
Why?
![Page 18: Eating Disorders and Substance Abuse](https://reader035.vdocuments.us/reader035/viewer/2022062500/5681525f550346895dc092bc/html5/thumbnails/18.jpg)
Misplaced Blame
• Eating disorders have traditionally been viewed as psychiatric illnesses that are strongly influenced by social pressures towards thinness.
• Family Twin and molecular genetic studies support substantial genetic influences on eating disorders
![Page 19: Eating Disorders and Substance Abuse](https://reader035.vdocuments.us/reader035/viewer/2022062500/5681525f550346895dc092bc/html5/thumbnails/19.jpg)
Twin Studies
Prevalence, Heritability and Prospective Risk Factors
for Anorexia Nervosa
31,206 twins born between 1935-1958
Arch Gen Psychiatry. 2006;63:305-312

The Genetics of Eating Disorders
• Activation of the heritability of eating pathology may be mediated by hormones in puberty.
• Cultural attitudes toward thinness have relevance to the psycho-pathology of eating disorder, but they are unlikely to be sufficient to account for the pathogenesis of these disorders

Psychotropic Medication in the Treatment of Eating Disorders
![Page 22: Eating Disorders and Substance Abuse](https://reader035.vdocuments.us/reader035/viewer/2022062500/5681525f550346895dc092bc/html5/thumbnails/22.jpg)
Comorbidity of Eating Disorders
• The lifetime rates of psychiatric comorbidity among patients with Anorexia are approximately 80%
• The lifetime rates of psychiatric comorbidity among patients with Bulimia are approximately 83%
![Page 23: Eating Disorders and Substance Abuse](https://reader035.vdocuments.us/reader035/viewer/2022062500/5681525f550346895dc092bc/html5/thumbnails/23.jpg)
Bulimia Nervosa: A Chronic Persistent Illness
Approximately 50% of bulimic patients including those who have been treated continue to show eating disorder features on long term follow up.
![Page 24: Eating Disorders and Substance Abuse](https://reader035.vdocuments.us/reader035/viewer/2022062500/5681525f550346895dc092bc/html5/thumbnails/24.jpg)
Treatment Recommendations
• Antidepressants:
SSRI’s: Higher than “usual” antidepressant dosage may be required.
- Prozac 60mg/day considerably more effective than 20mg/day for reducing binge eating behavior and vomiting frequency.
- Celexa 40-60mg, Zoloft 100 – 200 mg.- The only medicine approved by the
FDA for BN is Fluoxetine.
![Page 25: Eating Disorders and Substance Abuse](https://reader035.vdocuments.us/reader035/viewer/2022062500/5681525f550346895dc092bc/html5/thumbnails/25.jpg)
Binge Eating Disorder – Pharmacologic Treatment
Celexa 40-60 mg x 6 weeks
Prozac 40-80 mg x 6 weeks
Luvox 100-300 mg x 9 weeks
Zoloft 100-200 mg x 6 weeks
All medication resulted in significant reduction in binge eating and body weight.
![Page 26: Eating Disorders and Substance Abuse](https://reader035.vdocuments.us/reader035/viewer/2022062500/5681525f550346895dc092bc/html5/thumbnails/26.jpg)
Psychopharmacology
• Antidepressants alone rarely lead to complete remission of Bulimic symptoms.
• Controlled studies have failed to demonstrate any advantage to adding an SSRI to nutritional and psychosocial interventions in the treatment of malnourished patients with AN
![Page 27: Eating Disorders and Substance Abuse](https://reader035.vdocuments.us/reader035/viewer/2022062500/5681525f550346895dc092bc/html5/thumbnails/27.jpg)
A retrospective study of SSRI treatment in adolescent Anorexia nervosa: insufficient evidence for efficacy
In conclusion, our results challenge the efficacy of SSRI medication in the treatment of eating disorder psychopathology as well as depressive and obsessive-compulsive comorbidity in adolescent AN. Clinicians should be chary in prescribing SSRI in adolescent AN unless randomized controlled trials have proofed the benefit of these drugs.

Fluoxetine After Weight Restoration in Anorexia Nervosa
A Randomized Controlled Trial
This study failed to demonstrate any benefit from fluoxetine in the treatment of patients with Anorexia Nervosa following weight restoration. Future efforts should focus on developing new models to understand the persistence of this illness and on exploring new psychological and pharmacological treatment approaches.

Anorexia
• Is Anorexia Nervosa a Psychotic Disorder?- Patients believe they are overweight when
they are dramatically under weight
- Misperceptions about body size and shape
- “ED Voice” telling patients not to eat
• Atypical Antipsychotics have clinically been shown to be helpful with anxiety, food and distorted body image.

A New Model
Referenced EEG
![Page 32: Eating Disorders and Substance Abuse](https://reader035.vdocuments.us/reader035/viewer/2022062500/5681525f550346895dc092bc/html5/thumbnails/32.jpg)
The Referenced EEG
• A patient’s pretreatment QEEG data is obtained and statistically compared with similar QEEG data from patients with known medication responsivity.
• The result is a prediction of the patient’s likely responsivity to particular medications.
• This, in turn, informs the treatment strategy for the patient.
![Page 33: Eating Disorders and Substance Abuse](https://reader035.vdocuments.us/reader035/viewer/2022062500/5681525f550346895dc092bc/html5/thumbnails/33.jpg)
The rEEG Conjecture
• Resting EEG is stable• (abundant literature references support this)
• Resting EEG Changes with Medications• (Abundant literature references support this)
• Use Medications to normalize the EEG• (CNSR proprietary rEEG technology)
• Normalized EEG leads to normalized behavior• (CNSR clinical results)

Treatment Options
There are no research studies to support an optimal treatment program for patients with substance abuse and co-morbid eating disorders.
![Page 39: Eating Disorders and Substance Abuse](https://reader035.vdocuments.us/reader035/viewer/2022062500/5681525f550346895dc092bc/html5/thumbnails/39.jpg)
• A multidisciplinary approach has to recognize that eating disorders and co-morbid substance abuse are complex and require:– Integrated, concurrent medical, nutritional and psychiatric
treatment.– A combination of different types of therapy, including group
therapy, family therapy, individual counseling, dialectal behavioral therapy (DBT) and other methods of treatment.
– Treatment of co-morbidities. Co-morbidities exist more often than not. They should be assumed to exist until absence can be demonstrated.
– Changing treatment as the patient progresses.• Continuum of Care

• Aggressive treatment is crucial as these disorders affect children and young adolescents when they are most vulnerable, quickly destroying their foundation for psychological development.
